In this article, I want to show you how to hack a machine on the same network as you.
The situation is this one.
You want to infect a machine on the same network and take control of it.
For this we will apply the methodology we learned before (https://steemit.com/hack/@pierlave/learn-hacking-1-00-overview). This is just guidelines, you will adjust it depending on your task!
The environment is this one.
Kali machine ip 192.168.56.101.
Metasploitable machine ip unknown.
1) Reconnaissance phase
Scan the network with Nmap (tool for scanning https://nmap.org/ in Kali by default)
Open a terminal and pass the command (the * means all the ip's from 1 to 255).
nmap -sP 162.168.56.*
The metasploitable has the ip 192.168.56.102
Scan for the services running.
nmap -sT -v 192.168.56.102
Scan for the versions running
nmap -sV -v 192.168.56.102
After you have this information, you can try to exploit some services you know are vulnerable or you can do a vulnerability scan.
OpenVas is a free vulnerability scanner, you can install it by following this tutorial (https://www.kali.org/penetration-testing/openvas-vulnerability-scanning/)
You start a job to scan the ip 192.168.56.102 and it gives you a list of vulnerabilities and the severity.
I chose to exploit ftp vsftpd 2.3.4 on port 21.
2) Gaining access
In this phase, we will use what we learned from the scanning section to exploit the machine.
To exploit, we will use Metasploit (it's installed by default on Kali). We need to start PostgreSQL to make it work.
Open a terminal
service postgresql start
Search for an existing exploit for the vulnerability you want to exploit.
search vsftpd 2.3.4
We see an exploit we want to use
You can see the options for the exploit
Set the remote host to the victim's machine
set RHOST 192.168.56.102
Send the exploit
The exploit worked, you have now access to the machine.
Pass the command whoami to see what is your privilege level.
You are root! you have now complete control over this machine.
